ATTACHMENT FOR MOUTHPIEOEQ OF TELEPHONE-TRANSMITTERS- Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed August 1, 1906. s mi No. 328,732.

To (LZZ whom it may concern:

Be it known that I, WILLIAM CHARLES PLANK, a citizen of the United States, and a resident of Las Flores, B. 0., Mexico, have invented a new and Improved Attachment for Mouthpieces of Telephone-Transmitters, of which the following is a full, clear, and exact description.

This invention is an improvement 1n attachments for mouth ieces of telephonetransmitters. It is we 1 known by those accustomed to using telephones, especially ublic telephones, that the mouthpiece 0 the transmitter through constant use b a nuscellaneous class of people becomes oul and unsanitary.

The object of the invention is to provide means which will at all times keep the mouthpiece clean and odorless and avoid the objections above noted, as found in the usual telephone-mouthpiece.

Generally stated, the invention consists of numerous concentric removable linings of antiseptic paper so molded as to properly fit the mouthpiece of the transmitter and fastened therein and which is adapted to be readily removed sheet by sheet as the inner sheet becomes soiled or unsanitary.

'I he object is accomplished by my invention, one embodiment of which is hereinafter disclosed.

Reference is to be had to the accompany ing drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a view, partly in section, of an ordinary form of mouthpiece and transmitter With my improved attachment in place. Fig. 2 is a perspective view of the attachment; and Fig. 3 is a perspectiveview, partly broken away, of the split retaining-ring for holding the pa erin place.

The numeral l indicates any ordinary form of transmitter, having a mouthpiece 2 for containing my improved sanitary attachment 3, said attachment having an exterior,

form to snugly fit the mouthpiece, which is generally of conical formation, with a flared outer end, as shown. The attachment 3 consists of several leaves or removablelinings of thin antiseptic paper molded to the form of the interior of the mouthpiece, the outer leaf or layer of which is provided with extending' ears 5, three in number being shown at the flared end and preferably equally spaced about the periphery. Intermediate two of the ears 5 each leaf or lining is provided with an extension 6 and a row of longitudinal perforations 7, preferably in alinement with one edge of the extension and designed to form means by which the inner sheet may be readily torn out in a welling the ears 5 thereto when'the attachment is in position. The application of the attachment is normally shown in Fig. 1, with the ears 5 folded about the edge of the mouthpiece and clamped to ,it by means of the spring-ring 8. I

In the use of the attachment when the inner lining or leaf becomes soiled its project ing thumb-piece or handle 6 is grasped and the perforations torn through, which per mits the ready removal of the lining. This operation is repeated by the user of the telephone as often as is necessary, and when the complete series of linings is exhausted a new attachment or series may be placed in position.

It is evident that the various details of construction may be modified without de arting from the s irit of my invention, and desire to claim a 1 such as fall within a fair interpretation of the annexed claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. An attachment for mouthpieces, comprising a series of concentric linings of antiseptic paper, a plurality of ears projecting from the outer lining, a rojection extending from all the'linings, and a series of perfora tions in alinement with one edge of the pro jections for the purpose specified.
